DUBAI, United Arab Emirates (AP) — Oil prices jumped Monday as the widening war in Iran disrupted tanker traffic through the Strait of Hormuz, highlighting how important the passageway is to the world's oil supply.
The Strait of Hormuz is the narrow mouth of the Persian Gulf through which about a fifth of the world's oil passes. Tankers traveling through the strait, which is bordered in the north by Iran, carry oil and gas from Saudi Arabia, Kuwait, Iraq, Qatar, Bahrain, the UAE and Iran. Most of that oil goes to Asia.

Any disruption to traffic through the Strait of Hormuz is highly disruptive to the oil trade.
“The scale of what is at stake cannot be overstated,” said Hakan Kaya, senior portfolio manager at investment management firm Neuberger Berman. He said a partial slowdown lasting a week or two could be absorbed by oil companies. But a full or near full closure lasting a month or more would push crude oil prices, trading around $70 on Monday, “well into triple digits” and European natural gas prices “toward or above the crisis levels seen in 2022.”
Here’s what to know about the strait and the widening Iran war.
The Strait of Hormuz is a bending waterway, about 33 kilometers (21 miles) wide at its narrowest point. It connects the Persian Gulf to the Gulf of Oman. From there, ships can then travel to the rest of the world. While Iran and Oman have their territorial waters in the strait, it's viewed as an international waterway all ships can ply. The United Arab Emirates, home to the skyscraper-studded city of Dubai, also sits near the waterway.
The Strait of Hormuz through history has been important for trade, with ceramics, ivory, silk and textiles moving from China through the region. In the modern era, it is the route for supertankers carrying oil and gas from Saudi Arabia, Kuwait, Iraq, Qatar, Bahrain, the UAE and Iran. The vast majority of it goes to markets in Asia, including Iran's only remaining oil customer, China.
While there are pipelines in Saudi Arabia and the UAE that can avoid the passage, the U.S. Energy Information Administration says “most volumes that transit the strait have no alternative means of exiting the region.”
Threats to the route have spiked global energy prices in the past, including during the Israel-Iran war in June.
The strait is not officially closed, but tanker traffic has dropped sharply as satellite navigation systems were disrupted, data and analytics firm Kpler said on X on Sunday. The U.K. Maritime Trade Operations Center reported attacks on several vessels in the area on either side of the strait and warned of elevated electronic interference to systems that show where ships are.
A bomb-carrying drone boat struck a Marshall Islands-flagged oil tanker in the Gulf of Oman, which leads into the strait from the east, killing one mariner, Oman said.
Iran has been threatening vessels approaching the Strait of Hormuz and is believed to have launched multiple attacks.
Global shippers have issued service alerts saying they have suspended operations in the area. Danish shipping company Maersk, the world’s biggest shipping company, said Sunday it is suspending all vessel crossings in the Strait of Hormuz until further notice. Other ocean carriers including Hapag-Lloyd, CMA-CGM and MSC made similar announcements.
“No one is wanting to navigate it, and there’s no insurer who’s willing to stand behind any transport going through there right now.,” said Tom Goldsby, logistics chairman in the Supply Chain Management Department at the University of Tennessee. “Those ships that got stuck in the Gulf are not going anywhere. ... There’s also a whole host of ships that were heading into the Gulf to replace them, and of course they’re anchored or going elsewhere now."
Data and analytics firm Kplr estimated there are 70 laden oil tankers and 75 clean tankers, which carry refined oil products, in the Mideast Gulf, seemingly waiting to pass through. That’s roughly twice as many as usual, according to Kplr. Meanwhile, about 60 tankers are sitting just outside the Mideast Gulf, east of the Strait of Hormuz, in a holding pattern.
Iran temporarily shut down parts of the strait in mid-February for what it said was a military drill. Oil prices jumped about 6% in the following days.
The decision was a rare, perhaps unprecedented shutdown of the strait.
In past times of tension and conflict, Iran has at times harassed shipping though the narrows, and during the 1980s’ Iran-Iraq war, both sides attacked tankers and other vessels, using naval mines to completely shut down traffic at points. But Iran has not carried out repeated threats to close the waterway altogether since the 1980s, even during last year’s 12-day war when Israel and the U.S. bombarded Iran’s key nuclear and military sites.

HOUSTON (AP) — Artemis II’s astronauts closed out humanity’s first lunar voyage in more than half a century with a Pacific splashdown on Friday, blazing new records near the moon with grace and joy.
It was a dramatic grand finale to a mission that revealed not only swaths of the lunar far side never seen before by human eyes, but a total solar eclipse and a parade of planets, most notably our own shimmering Earth against the endless black void of space.
With their flight now complete, the four astronauts have set NASA up for a moon landing by another crew in just two years and a full-blown moon base within the decade.
The triumphant moon-farers — commander Reid Wiseman, pilot Victor Glover, Christina Koch and Canada’s Jeremy Hansen — emerged from their bobbing capsule into the sunlight off the coast of San Diego.
In a scene reminiscent of NASA’s Apollo moonshots of yesteryear, military helicopters hoisted the astronauts one by one from an inflatable raft docked to the capsule, hauling them aboard for the short trip to the Navy’s awaiting recovery ship, the USS John P. Murtha.
“These were the ambassadors from humanity to the stars that we sent out there right now, and I can’t imagine a better crew,” NASA Administrator Jared Isaacman said from the recovery ship.
Their Orion capsule, dubbed Integrity, made the entire plunge on automatic pilot. The lunar cruiser hit the atmosphere traveling Mach 33 — or 33 times the speed of sound — a blistering blur not seen since the 1960s and 1970s Apollo.
The tension in Mission Control mounted as the capsule became engulfed in red-hot plasma during peak heating and entered a planned communication blackout. All eyes were on the capsule’s life-protecting heat shield that had to withstand thousands of degrees during reentry.
Watching the drama unfold nearly 2,000 miles (3,200 kilometers) away, hundreds of jubilant workers jammed Mission Control to celebrate the splashdown. Astronauts’ families huddled in a viewing room, where cheers erupted when the capsule emerged from its six-minute blackout and again at splashdown.
The last time NASA and the Defense Department teamed up for a lunar crew’s reentry was Apollo 17 in 1972. Artemis II was projected to come screaming back at 36,170 feet (11,025 meters) per second — or 24,661 mph (39,668 kph) — just shy of the record before slowing to a 19 mph (30 kph) splashdown.
Until Artemis II, NASA’s fresh-from-the-moon homecomings starred only white male pilots. Intent on reflecting changes in society, NASA chose a diverse, multinational crew for its lunar comeback.
Koch became the first woman to fly to the moon, Glover the first Black astronaut and Hansen the first non-U.S. citizen, bursting Canada with pride. They laughed, cried and hugged all the way there and back, striving to take the entire world along with them.
Launched from Florida on April 1, the astronauts racked up one win after another as they deftly navigated NASA’s long-awaited lunar comeback, the first major step in establishing a sustainable moon base.
Artemis II didn't land on the moon or even orbit it. But it broke Apollo 13's distance record and marked the farthest that humans have ever journeyed from Earth when the crew reached 252,756 miles (406,771 kilometers). Then in the mission's most heart-tugging scene, the teary astronauts asked permission to name a pair of craters after their moonship and Wiseman's late wife, Carroll.
During Monday's record-breaking flyby, they documented scenes of the moon's far side never seen before by the human eye along with a total solar eclipse. The eclipse, in particular, “just blew all of us away,” Glover said.
Their sense of wonder and love awed everyone, as did their breathtaking pictures of the moon and Earth. The Artemis II crew channeled Apollo 8's first lunar explorers with Earthset, showing our Blue Marble setting behind the gray moon. It was reminiscent of Apollo 8’s famous Earthrise shot from 1968.
“We are back in the business of sending astronauts to the moon, bringing them back safely and to set up for a series more," Isaacman said. "This is just the beginning.”
Isaacman greeted the astronauts with hugs as they headed from the helicopters to ship’s medical bay for routine checks. They walked by themselves, refusing the wheelchairs offered them.
Their moonshot drew global attention as well as star power, earning props from President Donald Trump; Canadian Prime Minister Mark Carney; Britain's King Charles III; Ryan Gosling, star of the latest space flick “Project Hail Mary”; Scarlett Johansson of the Marvel Cinematic Universe; and even Captain Kirk himself, William Shatner of TV’s original “Star Trek.”
Despite its rich scientific yield, the nearly 10-day flight was not without technical issues. Both the capsule’s drinking water and propellant systems were hit with valve problems. In perhaps the most high-profile predicament, the toilet kept malfunctioning, but the astronauts shrugged it all off.
“We can’t explore deeper unless we are doing a few things that are inconvenient,” Koch said, “unless we’re making a few sacrifices, unless we’re taking a few risks, and those things are all worth it.”
Added Hansen: “You do a lot of testing on the ground, but your final test is when you get this hardware to space and it’s a doozy.”
Under the revamped Artemis program, next year’s Artemis III will see astronauts practice docking their capsule with a lunar lander or two in orbit around Earth. Artemis IV will attempt to land a crew of two near the moon’s south pole in 2028.
The Artemis II astronauts' allegiance was to those future crews, Wiseman said.
“But we really hoped in our soul is that we could for just for a moment have the world pause and remember that this is a beautiful planet and a very special place in our universe, and we should all cherish what we have been gifted,” he said.
